county of Waupaca, and State of Wisconsin, have invented new and useful Improvements in Transmission Mechanism for Motor- Driven Vehicles, of which the following" is a specification. I

lviy invention relates to improvements in transmission mechanism for motor (iriven vehicles, with especial reference to that class of vehicles in which the power is applied to all of. the four wheels.

The object of my invention to provide improved means for transmitting power from the engine to the live shafts of the front and rear axles with a view of securing greater stability, durability. and better cone trol than has heretofore been attained.

The transmission. gearing is enclosed in a casing, .1. which is connected with amain framebar 2 and sub-frame or auxihary frame bars 3. The casing 1 is divided into compartments 6 and 7, by a cross partition 8. The compartment. 6 contains the varialile speed and reversing mechanism and the compartment 7 contains the sub-transmission or driving connections and clutches or locking mechanism for the transmission shaft.

The variable speed and reversing gearing may be or anyorclinary construction. In the construction illustrated, motion is trans mitted from a driving shaft 10 to a clriven shaft 11, either directly through the clutch members 12 and 13, or indirectly" through The driving shaft 30 may be connected with gear wheel 1st, by means of clutch members 25 and 26, or it may be connected with gear wheel. .15 by clutch members 27 and. 28, or with wheel 16 by clutch members 29 and 30. the several pairs of clutch members being adaptecl for mutual engagement by proper movement of the clutch shifting collars 32' The arrangement oi the shafts, gears, and clutches in this variable speed: mechanism is Well known in this art and in itself constitutes no cart of my present in vention. Itis therefore not described with further particularity.

The driving members 35 and 36 of the transmission reach are actuatecl by tlifi'erential gear members 39 ancl at as shown in Fig. 6. The gear members 40 are mounted on suitable interior trunnionsgcarriecl by a casing: member 42, to the outer surface of which a sprocket pulley i3'is secured. Motion is transmitted from the shaft 11 to the sprocket pulley 43 through sprocket pulley at and belt 45., All of these parts arelocated within chamber? of the casing 1,; but the shafts and extend through the walls of the casing, to the exterior and havea.

universally jointed connection at 50 with the inclinecl members 5'1 of the transmission reach. Brake drums are mounted unonl the shafts 35:11:61 36 respectively, and brake hands 54 connected with the casing 1 are adapted to be set in binding relation upon these drums by means of levers 55 actuated from any desired point by means of flexible connections 56.

The gear wheels 39 of the differential gearing are nonrotatably, but loosely mounted on the shafts 35 and 36 respectively. The casing: 42 is provided with sleeve clutch members 60, the jaws 61 of which are adapted to be engaged by clutch members 62 1 mission to mount/2rd upon squared portions of the shafts. I and 36 respectively, and adapted to be moved longitudinally of their respective shafts into and out of engagement with the jaws 61. Each of these shifting, clutch members 62 is provided with a groove 65 loosely engaged by a forked arm 66 carried by a rock shaft 67, extending through the wall of easing 1. The rock shafts are provided with upwardly projecting-arms 68 which are connected by an extens ble, link 1n the form of a bar 69, having a se't'bf holes 70 and 71 for the coupling bolt 72 which connects it with one the link-is coupled at 71, the clutch members 62 are out of engagement and the transthe reach members is through the driven gear wheel of the differentlal gear set. When coupled at 72, botli clutches are in locking engagement with the casing clutches and the transmission shafts are directly connected with the driving or easing member 4-2 of the differential. This will be done only in case it is desired to uncouple one of. the transmission reaches and drive to either front or rear case any of the wheels are out of contact with the ground. As such conditions occur only occasionally, and the adjustment of the link 6.) may be made while the vehicle is atrcst. I prefer to not com licate the structure by providing means for effecting this adjustment from the drivers seat.

axle only, or in The lower ends of the inclined transmission respective ends. and

shaft members 51 are universally jointed at 75 with transmission shaft members 76, which enterthe axle dilferential casing '78, as shown in Fig. 4. The universal joints at 50 and 75 are preferably inclosed by nonmetallic flexibl coverings 80, as shown at the rear in Fig. 4, said coverings being omitted from'thefront portion of the transmissionreach in Fig. 4, in order to expose the joints 50 and 76. v

' The casing 1 is preferably-a one piece casing, having end caps 95,

another cap 85 at the top, affording access to the interior for the purpose of inserting.

ing 1 is therefore rigid in structure. and particula-rly so since it partition 8. This a feature of great iml' ortance. since thenicchanism inclosed within the casing is unaffected by the vibrations and torsional movements of the vehicle. all

the operation of the chain 45. a supply'of 4 011 being preferably imiintainedin the chum her 7.

Another important feature of my invenof the arms 68. When 81, 82 and 83 at its removing or repairing the mechanism incloscd therein. Said ,cas-' is reinforced by the tion is the provision of means for simultaneously engaging and disengagingthe driving members 35 and 36 of the transmission reach with the driving member of the differential gears through the medium of the clutch members 62, this feature being employcd in combination with means for indebrake bands 54, operating on the shaft drums 53. It is obvious that by separately applying a brake to each ofthe shafts 35'and 36, the relative movement of said shafts may be controlled, whereby skidding is prevented, such as might occur in case the front wheels encounter a considerably greater resistance than that encountered by the rear Wheels. Another advantage of the arrangement,

stopping the brakes will he applied simultaneously and with equal pressure.

these gears and I also attach great importance to the fact.-

most wholly obviated, and a silently run-- ning mechanism is produced.

It will be observed in Figs. 2 and 6, that the transmission shaft members 35 and 36 are provided with thrust bearing members 90 at their abutting ends, (Fig. 6) and the transmission reach members 51 and 76 are in slotted coupling relation at the universal joints 50 and 75. The shaft members 35 and 36 are squared where they pass through the gear wheels 3.) of the differential and are free. to slide in. such wheels into and out of end contact with each other. dinal movements of the transmission shaftm'embers therefore do not impart shocks to the differential gear wheels. The shaft members and 36 are also provided with collars 91 which have thrust bearing upon the bearing boxes 92 mounted in tliecasing cap 95 and which provide out bearings for the members 35 and 36. The collars 91 limit 36. Both the outer bearings 92 and the injner bearings 97 are carried by the cap 95, and are removable with it. i
